FRDM-KW41Z

Design with multi-mode (BLE/GenericFSK/802.15.4) radio solutions Kinetis® KW41Z/31Z/21Z MCUs for Wireless Applications The Kinetis KW41Z/31Z/21Z MCU family for wireless applications is the second multi-mode family in the Kinetis W series portfolio. Primarily used for automation and healthcare purposes, these MCUs enable low-energy and long-range connectivity. TARGET APPLICATIONS }} Home automation }} Healthcare –– Fitness monitoring –– Access control –– Home healthcare –– Appliances –– Institutional care –– Lighting control –– Medication asset –– Smart thermostats –– Patient monitoring –– Water heater control –– Curtain/window blind control –– Security systems }} Building automation –– Building control and monitoring –– Building HVAC control –– Fire/security –– Retail pricing management –– Security and access control –– Usage data collection OVERVIEW Integrating a Bluetooth® low energy (BLE) v4.2, Generic FSK (at 250, 500 and 1000 kbit/s) and IEEE® 802.15.4 compliant modem, Kinetis KW41Z/31Z/21Z MCUs can support multiple protocols running concurrently (time slice) in a single chip. These MCUs also integrate a buck-boost DC-DC converter, supporting a wide range of operating voltages from 0.9 V to 4.2 V, significantly reducing the peak current in receive and transmit modes. At the same time, this MCU family delivers an excellent link budget that ensures a long range of communication and high immunity to interference. KW41Z/31Z/21Z MCUs offer multiprotocol support which allow the system to concurrently operate in an 802.15.4 based network, like Thread, and a BLE network, eliminating the need for multiple radios, reducing system complexity and cost. With up to 512 KB of flash and up to 128 KB of SRAM on chip, KW41Z/31Z/21Z MCUs provide an option for running all your connectivity needs in a single device. Take advantage of the robust enablement package that includes the BLE host stack, generic FSK, Thread® stack, 802.15.4 MAC and Simple MAC (SMAC) software protocol stacks, RTOS, development tools and IDEs. These tools are designed for use with Kinetis KW41Z/31Z/21Z MCUs and are fully integrated in the Kinetis software development kit (KSDK).
